I doubt they will do treatments also. It's probably the bodies metabolic changes from cancer, not as much as nutrition. I was in a similar situation at stage 4, couldn't even raise my arm, could not stand, walk for over a year, and pulled through, but it took 6 months in a hospital, and nursing home just good enough to go home against medical advice, but no further treatments (rads) until 1.4 years later. Even after several recurrences, MO refused chemo, RO refused some rads too, even as far as last year, and I was 51. I hope for a miracle.
